Econometric Problems. Econometric problems, detection & fixes? Hands on problems. Regression Diagnostics . The required conditions for the model assessment to apply must be checked. Is the error variance constant? Are the errors independent? Is the error variable normally distributed?

Topic1. Some Illustrations of Econometric Problems. Econometrics attempts to measure quantitatively the concepts developed by Economic theory. and use the measures to prove or disprove the latter. Problem1: Estimating the demand curve of a product and measuring the price

Discussion, Questions, Identification of problems. Short term goals (2008): AROME : Put the existing soil OI analysis within SURFEX (mid 2008) (useful for HIRLAM groups using AROME)

Econometric Analysis. Week 10 Pooled and panel data models. Basics – data sets with both cross-section and time dimensions Pooled regressions and the use of time period dummies A note on Chow tests versus interactive dummies in the presence of heteroskedasticity

Econometric Modelling . Introduction. To examine some econometric results from various financial models To use the results to determine levels of significance of the variables and whether the results fit the theory To use the results for testing specific restrictions.

Econometric Analysis. Week 9 Limited dependent variables models. Binary choices and Limited Dependent Variables models The linear probability model logit and probit models Examples and results using PcGive

Econometric Modeling. More on Experimental Design. Angrist and Pischke Emphasize the identification of causal effects. Ask, “What is your identification strategy?” Point is to control for unobserved selection effects Offer several solutions: Randomized Controlled Trials

Econometric Modeling. How do we determine if econometric analysis is credible? Leamer (1983) focused on robustness: What is robustness? The sensitivity of the results to the functional specification and other key assumptions

Econometric Analysis. Week 7 Instrumental variables estimation and simultaneous equation models. Endogenous explanatory variables (regressors) and bias other sources of bias Instrumental Variables estimation valid instruments
